Over the last three months, I've carefully converted to the Arca mounts for all my tripods, replacing the heads etc. I've then gone and bought grips for all my cameras with arca bases so I can just slide them in and no issues.
Last week, I took all the arca bases off my camera to do some weight measurements (you can see where this is going, can't you).
Today, I loaded my cameras and a tripod into the car and have shot off for two weeks holiday in Scotland. Guess what I didn't bring!!!!
Bugger.
